Is this a positive answer?

My last period i had was on 19th dec-24th dec... since then I have not had any period at all. As my tracker says I am on cycle day 35 and 6 days late? Now last night I took a test and there is very faint 2nd line.... but a strong first line.... I have had heartburn on and off for 3 weeks, slightly sore boobs, small cramps and I am very tired? 😁😁
